Rear wheel supporting structure of tricycle

Abstract

The invention discloses a rear wheel supporting structure of a tricycle, comprising a tricycle frame and wheel seats and further comprising a transverse shaft, support arms, a fixed seat, a swing armand damping arms, wherein the transverse shaft is fixed to the frame; the left and right support arms are movably connected to the transverse shaft and the left and right rear wheel seats respectively; the fixed seat is fixedly connected to the frame, and the middle part of the swing arm is movably connected to the fixed seat through a swing shaft; and the left and right damping arms are movably connected to the middle parts of the left and right support arms respectively. The left rear wheel and the right rear wheel are supported at the same time through the transverse shaft, the support arms, the fixed seat, the swing arm and the damping arms; the left wheel and the right wheel can adaptively move up and down according to driving requirements and road conditions in the driving process; meanwhile, the swing arm swings along with the driving conditions so as to further coordinate movement of the rear wheels, such that comfort of passengers is improved. and the movement of the swing armcan be limited through a swing locking device according to the use condition, so that the follow-up performance of the tricycle in the running process is improved. In addition, during parking, the swing arm can be locked to provide effective support for the tricycle.

Description

technical field [0001] The invention relates to the technical field of motorcycles, in particular to a rear wheel support structure of a tricycle. Background technique [0002] Existing motorcycles usually adopt a two-wheel or three-wheel structure, and the wheel at the front is the steering mechanism of the motorcycle. The driver can change the direction of travel of the motorcycle by operating and turning the handlebar. The structure is easier for the driver to grasp. And traditional three-wheeled motorcycle generally adopts the structure that single wheel is in front, double-wheel is in the back, and the position of rear side two wheels is fixed, and shock absorber is arranged in part below the seat cushion, bumps and vibrations in the running of tricycle are controlled by shock absorber. Cushioning to improve driving comfort. But this kind of tricycle has poor anti-rolling ability and turning ability during driving, and vehicle roll will occur when the vehicle speed is...

AI Technical Summary

Problems solved by technology

However, this kind of tricycle has poor anti-rolling ability and turning ability during driving, and vehicle rollover will occur at a slightly higher speed, which is prone to rollover accidents, and at the same time, it has poor trafficability on bumpy roads

[0003] In the prior art, there are also tricycles whose rear wheels can swing according to the road surface, but the support structure of the existing tricycles is relatively complicated, and the locking operation is relatively troublesome, and it is also prone to overturning when parking
